AN EXPERIMENTAL RESEARCH ON PARTIALLY REPLACEMENT OF CEMENT IN M20 CONCRETE WITH RICE HUSK ASH AND WASTE PAPER SLUDGE

In this developing era concrete and cement mortar are widely used by the construction industry ,with this development .Large amount of industrial wastes are generated and if these wastes are not properly used it will create severe problems ,keeping the environment in mind, concrete engineers are trying to find some alternative materials which will not only replaces the cement content but also improves the strength of concrete. In this research work the Rice Husk Ash and waste Paper Sludge are used .The paper sludge which is the by product collected from paper mill and rice husk ash obtained from the rice processing units ,by adding these two products with concrete ,not only replaces the cement content but also increases the strength of concrete like compressive, flexural & split tensile strength etc .These two materials RSH & WPSA were incorporated with concrete with varying percentages of 2%,4%,8%, & 10% .The proper codal precautions were followed during the manufacturing the concrete cubes of 150 X 150 X 150mm and cylinders of size 150 mm X 300 mm casted with varying percentages of RHA & WPSA . The total number of specimen which were prepared 78 cubes and cylinders were casted with proper curing and the series of tests were conducted on these specimens like Split tensile ,Flexural ,Compressive strength ,Normal consistency test etc .
